Tristan
(Received Pronunciation) - IPA(key)
Tristan (/ˈtrɪs.ˌtæn/) is the captive moon of Isolde. Given that the two moons possess identical mineral deposits, it is possible that they were once a single unified body, or otherwise originated from the same source. Tristan is unusual in that, despite its weak gravity, it possesses a blue and orange atmosphere as tall as moons many times its size, and its form is nearly obscured by the diffuse glow of its upper atmosphere. This fog persists to the ground level of the moon, and it is practically impossible to see across long ranges.
Nomenclature
Tristan is the hero of the Arthurian legend of Tristan and Isolde. Based on a Celtic legend, the tale is a tragedy about the illicit love between the Cornish knight Tristan and the Irish princess Isolde in the day of King Arthur. It depicts Tristan's mission to escort Isolde from Ireland to marry his uncle, King Mark of Cornwall. On the journey, Tristan and Isolde ingest a love potion, instigating a forbidden love affair between them.
